What if there is no switch in the hotel central air conditioner?

If the central air conditioner in the hotel has no switch, you should first report the problem to the front desk or room service center and ask for their assistance. Before waiting for the arrival of maintenance personnel, the following measures can be taken:

1. Close the doors and windows of all rooms, keep the air circulating, and prevent the outside hot air from entering the room.

2. Use a fan or small air conditioner in the room to improve air circulation.

3. Try to open all the doors and windows in the room to promote air circulation, and find a cool place in the air conditioning equipment in or near the hotel, such as a shopping mall.

If there is no switch and the temperature is very high, you can ask the hotel to change rooms or (in extreme cases) check out to provide you with a more comfortable accommodation environment.

In short, in this case, the most important thing is to reflect the problem to the hotel staff in time and cooperate with them to solve the problem to ensure that your stay experience will not be affected.
